Advanced Reactors

Leaders from Holtec International and Hyundai Engineering & Construction gathered at the Palisades site in western Michigan today to announce an “expanded cooperation agreement” to build a 10-GW fleet of Holtec-designed SMR-300s in North America. That fleet’s first builds would be at Palisades, where Holtec is now focused on restarting the site’s shuttered 777-MWe pressurized water reactor by the end of this year. Under the “Mission 2030” plan launched today, Holtec would then build a pair of SMR-300 PWRs at the Palisades site—targeting operation in 2030.

U.K.-based Core Power has announced that it intends to develop a maritime civil nuclear program anchored in the United States with the goal of bringing floating nuclear power to market by the mid-2030s. The program, called Liberty, is to encompass the modular construction of advanced reactor technology and create the regulatory and supply chain frameworks needed to begin the mass production of floating nuclear power plants (FNPPs) on a global scale.

The International Energy Agency has published a new report examining opportunities for the nuclear power industry to address concerns related to energy security and climate change. The Path to a New Era for Nuclear Energy explores areas of policy, innovation, construction, and financing with an emphasis on investment-related issues regarding small modular reactors.

The IEA report describes encouraging developments taking place in the nuclear energy industry, such as increasing investment, technology advances, and supportive policies in many countries. But it also notes that certain key challenges need to be overcome if nuclear energy is to meet the needs of rising electricity demand, including demands from artificial intelligence and data centers. In addition to examining the present global status of nuclear power, the report evaluates the long-term outlook, quantifying expected capacity and investment through 2050.

Texas A&M chancellor John Sharp has announced that the university could soon become a home to small modular reactors from four advanced nuclear companies: Kairos Power, Natura Resources, Terrestrial Energy, and Aalo Atomics.

To better educate customers and stakeholders on its technology, NANO Nuclear Energy has opened a new demonstration facility in Westchester County, N.Y., that offers an up-close look at nonnuclear parts and components of the four microreactors the company has in development.

A team of innovative companies has plans to bring floating nuclear power plants to U.S. ports.

Core Power, a maritime and nuclear technology company, announced in January a new partnership in with naval architecture company Glosten. The pair is working on a design for a floating nuclear power plant (FNPP) that could generate up to 175 gigawatt-hours of clean electricity annually and provide clean power to ships, equipment, and port vehicles, Offshore Energy reported.

A 1,300-acre site left undeveloped on the shores of Lake Ontario four decades ago could see new life as the home to a large nuclear facility.

The Department of Energy has announced a competitive funding opportunity of up to $13 million to help first movers defray the licensing costs of bringing advanced nuclear reactors to market.

“SMRs present a viable opportunity for Indiana to transition to a cleaner, resilient, and diversified energy future. Successful deployment of SMR technology requires a careful balance of economic, regulatory and social considerations along with development of the technology.” Those are among the conclusions of a comprehensive study conducted on small modular reactors primarily by researchers at Purdue University and funded by the Indiana Office of Energy Development.

Advanced nuclear company Oklo and data center developer Switch closed out 2024 by announcing a new partnership to deploy 12 GW of advanced nuclear power under a master power agreement.

TerraPower announced this week that it has awarded the major manufacturing contracts for its Natrium plant reactor enclosure system.

These vendor awards help advance deployment and commercialization of what the company is calling “America’s first advanced reactor,” according to TerraPower’s press release. The news is also a major milestone in establishing the advanced nuclear supply chain, the company added.

BWXT Canada, a subsidiary of BWX Technologies, is partnering with Westinghouse Electric Company to build new nuclear projects in Canada and globally.

American start-up Last Energy has received a letter of interest from the Export-Import Bank of the United States (EXIM), confirming the bank’s willingness to move forward with due diligence for $103.7 million in financing for the company’s project in southern Wales.

Westinghouse Electric Company’s eVinci Advanced Logic System (ALS) Version 2 (v2) instrument and control (I&C) platform has received approval from the U.S. Nuclear Regulatory Commission through a final safety evaluation report on two topical reports.

The eVinci is now the first and only microreactor with an I&C system approved by the NRC, which opens a path to autonomous operation. The approvals also allow the ALS v2 platform to be used by any reactor currently in the U.S. fleet.

Aalo Atomics and the Department of Energy announced yesterday that the company has worked with Battelle Energy Alliance and the DOE’s Idaho Operations Office to develop a plan—described as “provisional,” “potential,” and “tentative”—to grant Aalo a one-acre plot of land at Idaho National Laboratory site to build a new facility that would house an experimental reactor. Aalo hopes the reactor, dubbed Aalo-X, will help the company license and commercialize Aalo-1, a 10-MWe sodium-cooled reactor.

Radiant Industries has announced a $100 million Series C funding round to be used primarily to complete its Kaleidos Development Unit (KDU) microreactor for testing in Idaho National Laboratory's Demonstration of Microreactor Experiments (DOME) facility within two years.

The Nuclear Regulatory Commission announced yesterday that it has directed staff to issue construction permits to Kairos Power for the company's proposed Hermes 2 nonpower test reactor facility to be built at the Heritage Center Industrial Park in Oak Ridge, Tenn. The permits authorize Kairos to build a facility with two 35-MWt test reactors that would use molten salt to cool the reactor cores.

Oklo Inc. announced yesterday that it has partnered with “two major data center providers” under letters of intent (LOIs) to deliver up to 750 MW of power from multiple 15 MW or 50 MW Oklo microreactors at data centers in “select” undisclosed U.S. markets.

FLiBe—a mixture of lithium fluoride and beryllium fluoride—is not an off-the-shelf commodity. The Department of Energy suspects that researchers and reactor developers may have a use for the 2,000 kilograms of fluoride-based salt that once ran through the secondary coolant loop of the Molten Salt Reactor Experiment (MSRE) at Oak Ridge National Laboratory.

The Nuclear Regulatory Commission has published a proposed rule that has been almost five years in the making: Risk-Informed, Technology-Inclusive Regulatory Framework for Advanced Reactors. The rule, which by law must take its final form before the end of 2027, would establish risk-informed, performance-based techniques the NRC can use to review and license any nuclear power reactor. This is a departure from the two licensing options with light water reactor–specific regulatory requirements that applicants can already choose.
